Here is what it says to do if the hands don't match up with the display time (usually happens after you change the battery).
First, you must locate the buttons on the watch.
The "A" button is at the 2 o'clock position (upper right). The "B" button is at the 10 o'clock position (upper left) The "C" button is at the 8 o'clock position (lower left) The "M" (mode) button is at the 4 o'clock position (lower right), and is the only button you can pull out to set the times, calendar and programming.
To RESET the watch and do the ZERO POSITIONING after changing a battery or having a display error, do the following.
RESET 1. Pull the "M" button out to the setting position. 2. hold down the "A", "B", and "C" buttons simultaneously for 3 seconds, then release them. All digit segments will turn on and display completely.
ZERO POSITIONING 1. Press the "B" button and all the segments in the digital time will reset to zero, with "UTC" showing in the main digital window. 2. Zero the "UTC" minute and hour hand (located in 12 o'clock sub-dial) to the 24 o'clock maker (straight up). Button "A" will move the hands clockwise, and button "C" will move the hands counter clockwise. 3. Press button "B" - "HR" shows in the main digital window. Adjust the main (large) hour hand to the 12 o'clock (midnight) position using "A" and "C" buttons. At the same time, observe the synchronized 24 hour hand (small dial to the left of the main dial), to insure that it also moves to point to "24". 4. Press button "B". "MIN" shows in the display window. Adjust the large minute hand to also point to the 12 using the "A" and "C" buttons. 5. Push the "M" (mode) button back in to its normal position. The watch beeps and at the same time the hands jump slightly. ALL RESET and ZERO POSITIONING are now complete. 6. Reset the time, calendar and other modes. To set the time. Note that changing the time in any of the cities will automatically update the time for all the cities. 1. Press the "M" button to move the mode hand to (TME) 2. Press either the "A" or "C" button to move to the desired city. 3. Pull the "M" button out to the setting position. 4. Press the "A" button. SECONDS will blink. Set them with "C". 5. Press the "A" button again, and MINUTES will blink. Set them with the "C" button. 6. Press the "A" button again, and HOURS will blink. Set with the "C" button. 7. Press the "A" button again, and 12 or 24 hours tim format will appear. 8. Push in the "M" button to its normal position. To set thecalender 1. push the "M" button to move the mode hand to (CAL) 2. Set the city using the "A" or "C" buttons. 3. Pull out the "M" button to the "setting" position. The numbers of the "month" starts to blink. this is an "american" date system with the month first, day second, and year third. Use "C" button to adjust the month. 4. Push the "A" button. The date (day) will flash. Adjust with the "C" button. 5. Push the "A" button. The YEAR flashes. Adjust with the "C" button. 6. Push the "M" button back in. The calender is simultaneously adjusted for all cities.
Couple of other "tips". Switching the time on the digital display with the time shown on the hands: 1. Press the "M" button until the mode hand is in (TME) or (CAL) mode. 2. Pressing the "A" and "C" button together. The time will switch the between the main hands (analog) and the digital display. Temporary Hand Retraction Pressing and holding the "B" button will move the hands out of the way of the display. Repressing the "B" button will put the hands back at the correct time.

if it is the Batman watch that has a secret screen that lights up when you pushed the bottom middle of the watch face this is what worked for me.I call that secret middle button the mode button.push and hold that secret button on the watch face until the hour side of the time starts to blink. let go when you see the hour blink and then you can keep pressing to change the hour. to change the minute I let it go back into sleep mode then press and hold the secret button on the watch face and when it starts to blink let go for half a second and then press down and hold that button again and a minute numbers should start blinking. when they start blinking let go and then push once for each minute. it seems once you start one of these cycles letting go for half a second and then pressing and holding the mode button works. you'll have to experiment with how long to let go and then push.

First, find the regular time mode by pressing the MODE button until the time (with the date at the top) shows.

Press & hold the SET button until the word ENTER disappears and
is replaced by the word TIME. Release that button. You'll notice that at
the top of the display, the words SET T1 or SET - T2. This is where you
select between setting the 1st time zone or the 2nd time zone. Select
between T1 or T2 by pressing the RECALL button or the STOP/RESET button.

Press either the MODE or the START/SPLIT button. You'll notice that
whatever is blinking is what you can change. You can make the changes by
pressing either the RECALL or the STOP/RESET button. You can change the
Seconds, the Hours, the Minutes, the Month, the Date, the Year, and
choose between 12 hour (civilian) or 24 hour (military) time. If you
keep MODE or START/SPLIT button, you will go through all the things you
can change and start again at the beginning. The START/SPLIT button goes
through these things forward, and the MODE goes through the backwards,
so if you pass something and want to back up, just switch buttons. In
the same way, the RECALL changes things by making them larger, and
STOP/RESET changes them by making them smaller, so if you accidentally
pass the number you're trying to set it to, just switch to the other
button and go back.

Hold the reset button (upper left button) until the seconds start to blink. To go to the hours, push the mode button (lower left button). To set the hour, push the ST/STP button (upper right button) to the desired hour. To go to the minutes, push the mode button again, set the minutes with ST/STP button. To go to the date, push the mode button, set with the ST/STP button. Once done, simply hit the reset button to complete. Hope this helps!

When looking at the face, you have 4 pushers. Top left is for regatta function countdown. Top right is regatta function start-stop-reset. Bottom left is Hours-Minutes and Nite Lite. Bottom right is regatta function "catch up". Assuming that you want to set Hours and Minutes, press and hold the bottom left for 3 seconds...Hours will start blinking, press the pusher successively until the desired hour is reached. Then wait until it stops blinking. To set minutes, press and hold for 3 seconds, the hours will again begin to blink, then release and re-press for an additional 3 seconds and the minutes will blink, Then press successively until desired minutes have been reached. Stop pressing and wait until the blinking has stopped. Once it has stopped blinking your time has been successfully registered. Good Luck. Hope this helps!

1 There should be four buttons: mode, reset, start and light. Find the mode button and press it three times until it is in the set time mode.

2 Find the reset button, which usually is located on the bottom right side of the watch face, and hold it until the time starts blinking.

3 Press the start button to change minutes.

4 Press the reset button again to switch to hours.You will know it worked when the hour starts blinking instead of the minutes.

5 Press the start button to change the hour. The watch can handle two modes: standard and military. As you press start, the hour will change from AM to PM, noted by an "A" or a "P" in the top right. When you get through 24 hours, the watch will change to military time and an "H" will be displayed instead of "A" or "P." Keep pressing start to go through another 24-hour cycle and it will revert back to standard time.

go to Buliva web site and look for the chorograph 561/598
FEATURES
1. Hours, minutes, seconds and date display.
2. 60 minute Chronograph (CHRONO) with minutes and
seconds display.
3. 24 hour hand, permanently synchronized with the normal
12 hour hand.
A. SETTING THE TIME
1. Pull the crown out to position “3” (See diagram). If the crown has
a “screw-down” lock, then unscrew the crown lock first by turning
the crown toward you, then pull it to position “3”. Do not forget to
screw the crown back “IN” after all setting is completed.
2. Turn the crown towards you (hands moves clockwise) until the
date changes at approximately midnight.
3. Continue turning the hour and minute hands to the correct time.
If it is afternoon you must go past 12 o’clock again (noon) to set
the correct time.
4. When the correct time is set,push crown back to position “1”.
B. SETTING THE DATE
1. Pull crown to position “2”(See proceeding diagram).The watch
will continue to run.
2. Turn the crown away from you until the correct date appears.
3. Once the date is set, push the crown back to position “1”.
Note: Do NOT set the date between the hours of 8:00 PM and
3:00 AM.This would not damage the watch,but the date may need
to be reset later.
C. CHRONOGRAPH (CHRONO) ADJUSTMENT
If the chrongraph second hand is not positioned at the proper
starting position (12 o’clock or “zero” position), use the below
procedure.It does not need to be repeated unless the watch
receives an impact sufficient to move the hand out of position, or
the Battery has been changed.
1. Pull crown out to position “3”.
2. Push button “A” to move the Chrono Second hand (long hand) to
the “0” or 12 o’clock position. Each button push will move the
hand one step – BUT holding the button down will advance the
hand rapidly.
3. Push crown back to position “1”.
D. USING THE CHRONOGRAPH (CHRONO)
Note: The maximum chrono reading is 60 minutes, However the
chrono will continue running once 60 minutes has passed. The
resulting one hour periods may be added together mentally to keep
track of longer periods.
For example – If you know that approximately one hour has
passed since you started the chronograph, and the chrono reads
25 minutes, then you know that the chrono has been running 60
minutes plus 25 minutes, which is one hour and 25 minutes.
1. Push Button “A” to start the chronograph. Push button “A” again
to stop the chronograph.
2. Push button “B” to return the two chronograph hands to the
“Zero” or starting point.
3. The Chronograph can be stopped and started again
(Button “A”), repeatedly, to “ADD” times together.

Part 2:
Press Lap/Reset button once again to make hours blink
Cycle through hours using Start/Stop Button

(for this part, it's a bit tricky. Hours can be displayed in AM, PM, or 24 hour duration. AM is represented by "A", PM is shown with "P" and 24 hour mode is shown with "H", so keep an eye in the seconds window when setting your hour so you know for sure if you have the right hour)

When your done setting minutes and hours, press mode button again till you get to main screen
A helpful hint is to remember when setting up anything in this watch, mode will cycle through the different screens, lap/reset will change the value of whatever your modifying (AKA minutes/hours) and start/stop scrolls through the different fields.
